I had CuteFTP and Filezilla so far… both have good and bad points and i think none is perfect.
What FTP software are you using to upload your files to the server?
filezilla nothing wrong with it, it does the job!
i also use filezilla no problems here
filezilla here also. It has a problem sometimes – it says it’s connected but there are no connections but I think it’s more servers problem.
